Aztec tower of skulls revealing ancient secrets

BBC – Tales of the tower of skulls which struck fear into the hearts of Spanish conquistadors have been passed down through the generations in Mexico. For the next 500 years, the skulls lay undisturbed underneath what was once the Aztec capital Tenochtitlan, but is now Mexico City.
